Som Tum (Green Papaya Salad)

Ingredients

• 400 g green papaya, unripe, no trace of yellow in flesh or skin; shredded on a box grater or julienned by knife into 3–4 mm matchsticks
• 30 g dried shrimp (goong haeng), lightly toasted before use
• 80 g long beans (tua fak yao), cut into 3 cm pieces
• 100 g cherry tomatoes, halved
• 2–5 bird's eye chillies, taste before use and adjust quantity to preference
• 2 garlic cloves
• 1.5 tbsp fish sauce
• 2 tbsp lime juice, freshly squeezed
• 1 tbsp palm sugar

Method

1. 1
   Lightly toast the dried shrimp in a dry pan until fragrant, so the heat drives off residual moisture and concentrates the briny, savoury depth that anchors the whole dressing. Set aside. Pound the garlic and chillies in a large stone mortar to a rough paste — not smooth — so the discrete fragments of chilli skin hold pockets of heat that release unevenly in the finished salad, giving each mouthful a slightly different intensity.
2. 2
   Add the toasted dried shrimp to the mortar and pound briefly — four or five strokes — so the shrimp break open and surrender their flavour into the paste without collapsing to a powder that would cloud the dressing. They should remain as lightly crushed, identifiable pieces.
3. 3
   Add the long bean pieces and bruise with the pestle — do not pound smooth — so the beans split and crack along their length, allowing them to absorb the dressing while keeping enough body to provide resistance against the tender papaya. The beans should remain as identifiable pieces.
4. 4
   Add the palm sugar, fish sauce, and lime juice, then stir to dissolve the sugar. Taste the sauce now — this is where the dish lives or dies — because the papaya will dilute and soften every element once it enters the mortar, so the sauce must read as intensely assertive at this stage: sharply sour, aggressively salty, and pronouncedly sweet in rapid sequence, at least fifty per cent more forceful than the desired finish. A sauce that tastes balanced here will produce an under-flavoured salad; adjust the ratios before proceeding.
5. 5
   Add the shredded papaya in two or three handfuls, bruising and tossing with the pestle and a spoon — never pounding — so the shreds are lightly compressed enough to absorb the dressing without splitting apart and turning limp. The salad is ready when the shreds are evenly coated, glistening, and carry the full flavour of the sauce.
6. 6
   Add the halved cherry tomatoes and bruise gently — one or two strokes — so they release their juice into the mortar and brighten the dressing with a fresh, acidic note without dissolving into it. Toss once more to distribute evenly.
7. 7
   Taste the finished salad to confirm that all four tastes — sweet, sour, salty, hot — arrive simultaneously within one to two seconds. Transfer immediately to plates, as the papaya must remain crunchy-firm; any softening tells you the salad has rested too long and the papaya has begun to weep. Serve within five minutes of assembly.
